Hi,

I have a view which joins multiple tables to give me a result. It takes more than a minute to give me the result on psql prompt when I select all the data from that view.
The single CPU which is used to run this query is utilized 100%.Even if I fire a count(*) it takes 10 Sec. I wanted to know if there is anything we can do to speedup this query below 1 sec.
